Hi community,

 

I have some questions about i.MX53 USB_OTG_ID pin.

Please see my questions as following.

 

[Q1]

Please see Table 113 in IMX53CEC (Rev.6).

It shows the I/O buffer type of USB_OTG_ID is ANALOG25.

And power rail of it is USB_OTG_VDDA25, USB_OTG_VDDA33.

I want to know the relation ship between them.

Is ANALOG25 supplied power by USB_OTG_VDDA25?

If yes, how about USB_OTG_VDDA33?

 

[Q2]

Does i.MX53 USB_OTG_ID pin have a pull-down resistor?

If yes, could you let me know the resisotor value?

 

[Q3]

Could you let me know VIH and VIL and absolute maximum range of i.MX53 USB_OTG_ID pin?

Or it does not have VIH and VIL since this pin is analog?

 

 

Best Regards,

Satoshi Shimoda
